...CENTER OF ALBERTO MOVING ACROSS SOUTHWEST INDIANA...
...HEAVY RAINFALL THREAT CONTINUES...


SUMMARY OF 1000 AM CDT...1500 UTC...INFORMATION
-----------------------------------------------
LOCATION...38.7N 87.4W
ABOUT 80 MI...129 KM SW OF INDIANAPOLIS INDIANA
MAXIMUM SUSTAINED WINDS...30 MPH...45 KM/H
PRESENT MOVEMENT...NNE OR 24 DEGREES AT 17 MPH...28 KM/H
MINIMUM CENTRAL PRESSURE...997 MB...29.44 INCHES


WATCHES AND WARNINGS
--------------------
Flash Flood Warnings are in effect for portions of western
Kentucky as well as from extreme northeast Georgia to western North
Carolina. Flash Flood Watches are in effect for portions of the
southern Appalachians and Lower Ohio Valley.


DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Tropical Depression Alberto
was located near latitude 38.7 North, longitude 87.4 West. The
depression is moving toward the north-northeast near 17 mph (28
km/h) and this motion is expected to accelerate today.

Maximum sustained winds are near 30 mph (45 km/h) with higher
gusts. The system will transition to an extratropical wave cyclone
as the remnant circulation comes under the influence of an upper
level trough moving across the Great Lakes and southern Canada
through Thursday.

The estimated minimum central pressure is 997 mb (29.44 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Additional rainfall of 2 to 4 inches, with isolated
higher amounts, will be possible northward along the
Illinois/Indiana border into the Lower Peninsula of
Michigan. Flash flooding and rapid water rises on creeks and streams
will remain a possibility across these areas.

WIND: A few wind gusts may approach tropical-storm force (34 knots
or 39 mph) across western and central Indiana today.

Banding and structure look better now than they did even over AL. It's ABSURD seeing this hold together as well as it has this far inland Super fascinating storm.

my Nik called Alberto a "Flopical Storm" for us here in Clearwater, FL, after so little impacts were experienced. I like that term! lol. As expected, only occasional rains (no worse than daily thunderstorms) and light winds were experienced with his passby in the GOM. The heaviest/worst rains were actually yesterday and today from all that moisture still pumping up from the south. Winds on Monday were the strongest for us, with higher sustained and tropical storm gusts.
Though none of it was anywhere near what Irma was for us last year. Happy for that!!

[cycloneye]

More impressive as time goes by.

[WeatherGuesser]

What happens if this thing gets off the coast into the Atlantic with the structure as intact as it is now?

[Kazmit]

Alberto is one of the strangest storms I've ever tracked. It's more organized over land than it was over water.

I wonder if we'll have another season of weird storms. I have to admit, I love the weird ones.

[aperson]

Saved radar loop. Frontal passage is visible and looks to me like Alberto is finally about to undergo ET transition

More impressive as time goes by.

That is insane. Looks like Photoshop.
